2008 Fiat Ducato Headlights wont switch off

Model 40 maxi 160 M-Jet. With the headlight switch in the off position as soon as you turn on the ignition the relay in the cab fuse box clicks and the headlights, tail lights and sidelights come on and stay on. The 3 position switch does nothing but you
can select full beam and use the indicators. I have disconnected this entire switch unit on the steering column and the lights still come on. I have checked the relay on a tester and its fine. I have checked the engine fuse box and that is dry. Can anyone
advise or help please, also if you have access to other forums can you please post this question and feed back

I have noticed also that the water channel above the bonnet on the drivers side has a water exit hole with a pipe connected to channel the water away from the engine compartment. On the far left hand  passengers side there is a hole in the channel but no
pipe connected so water does go into engine compartment is this how it should be and could it be relevant to the problem above.

Thanks

    Is it possibly a way for Fiat to have fitted day time running lights to your vehicle? I have the option on my 07 Mercedes to have my lights on all the time irrespective of the light switch position. Some countries require vehicles to have lights on at all
    times. Maybe it's one of those daft combinations of switch presses will turn them off & operate via the switch.  ???

    Thanks. I have checked this out and day time running lights are not fitted on my motor home. This is indicated by only having a 3 way lighting switch, I believe if they are fitted then the switch has a fourth position. Also with dayime running I think only
    the front lights come on.

    DRL was perhaps the wrong word. My car doesn't have them either but can still have the lights on constantly whatever the switch position.

    Thanks. I have looked at the manual again today and there is nothing in there in regard to keeping the lights on with the switch in the off position.  If anyone knows of a setting on the 2008 Fiat Ducato which enables or disables this function please let
    me know.  I only took the vehicle for an MOT first run of the season and this occured when I picked it up.

    A quick Google search would suggest it's the switch at fault.

    Hi All

    I know this is an old thread ...  but can you remember what was the outcome. Just had our 2008 Ducato Tribby MOT and serviced - now cant turn off the headlights!! Will obviously get back to the garage - but any clues would be really welcomed.

    Thanks 

    P&H
